关于Rails和Apache的协作
我正在使用Vagrant、VirtualBox和CentOS6进行学习，目的是通过apache使rails能够运行。
問題の投稿はありましたが、うまく機能したため、修正された内容に変更します。
エラーの原因は、passengerをsudoでインストールしたため、systemのruby 1.8.7に対応したapacheがビルドされてしまったことでした。
所有的操作。
> vagrant box add centos664 http://developer.nrel.gov/downloads/vagrant-boxes/CentOS-6.4-x86_64-v20130731.box
> mkdir centos6
> cd centos6
> vagrant init centos664
Vagrantfileを編集
# using a specific IP.
config.vm.network :private_network, ip: "192.168.33.30"
> vagrant up
> vagrant ssh
更新yum并安装vim。
$ sudo yum -y update
$ sudo yum -y install vim
将文本转为日语
$ sudo vim /etc/sysconfig/i18n
LANG="ja_JP.UTF-8"
$ sudo reboot
创建具有root权限的用户
$ sudo usermod -G wheel vagrant
$ sudo visudo
## Allows people in group wheel to run all commands
%wheel ALL=(ALL) ALL
wheelグループを有効化する
安装apache
$ sudo yum -y install httpd
$ sudo service httpd start
$ sudo chkconfig httpd on
安装必要的工具
$ sudo yum -y install gcc gcc-c++ openssl-devel zlib-devel make patch git gettext perl rpm-build
$ sudo yum -y install httpd-devel curl-devel ncurses-devel gdbm-devel readline-devel sqlite-devel ruby-devel
安装rbenv
$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ exec $SHELL -l
$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
$ sudo .rbenv/plugins/ruby-build/install.sh
安装Ruby 1.9.3
$ rbenv install -v 1.9.3-p484
$ rbenv rehash
将Ruby 1.9.3设置为全局。
$ rbenv global 1.9.3-p484
$ rbenv versions
$ sudo chmod o+x /home/vagrant
乘客的安装
$ gem install passenger --no-ri --no-rdoc -V
$ rbenv rehash
在Apache中安装Passenger模块。
$ passenger-install-apache2-module
The Apache 2 module was successfully installed.
Please edit your Apache configuration file, and add these lines:
LoadModule passenger_module /home/vagrant/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.25/buildout/apache2/mod_passenger.so
PassengerRoot /home/vagrant/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.25
PassengerDefaultRuby /home/vagrant/.rbenv/versions/1.9.3-p484/bin/ruby
After you restart Apache, you are ready to deploy any number of Ruby on Rails
applications on Apache, without any further Ruby on Rails-specific
configuration!
Press ENTER to continue.
--------------------------------------------
Deploying a Ruby on Rails application: an example
Suppose you have a Rails application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:
<VirtualHost *:80>
ServerName www.yourhost.com
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /somewhere/public
<Directory /somewhere/public>
# This relaxes Apache security settings.
AllowOverride all
# MultiViews must be turned off.
Options -MultiViews
</Directory>
</VirtualHost>
And that's it! You may also want to check the Users Guide for security and
optimization tips, troubleshooting and other useful information:

首先，执行rbenv rehash。
$ rbenv rehash
创建乘客配置文件.passenger.conf
$ sudo vim /etc/httpd/conf.d/passenger.conf
请将以下内容写入
LoadModule passenger_module /home/vagrant/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.25/buildout/apache2/mod_passenger.so
PassengerRoot /home/vagrant/.rbenv/versions/1.9.3-p484/lib/ruby/gems/1.9.1/gems/passenger-4.0.25
PassengerDefaultRuby /home/vagrant/.rbenv/versions/1.9.3-p484/bin/ruby
Header always unset "X-Powered-By"
Header always unset "X-Rack-Cache"

Header always unset "X-Runtime"
修改httpd.conf
$ sudo cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.org
$ sudo vim /etc/httpd/conf/httpd.conf

<VirtualHost *:80>
RailsEnv development
PassengerEnabled on
ServerName 192.168.33.30
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /home/vagrant/rails_app/sample/public
